FFmpeg 'libavcodec/rawdec.c' Out Of Bounds Denial Of Service Vulnerabilities

7 Apr. 2015

Summary

The raw_decode function in libavcodec/rawdec.c in FFMpeg before 2.1.6, 2.2.x through 2.3.x, and 2.4.x before 2.4.4 allows remote attackers to cause a denial of service (out-of-bounds heap access) and possibly have other unspecified impact via a crafted .cine file that triggers the avpicture_get_size function to return a negative frame size.

Vulnerable Systems:
*FFMpeg before 2.1.6, 2.2.x through 2.3.x, and 2.4.x before 2.4.4

Immune Systems:
* FFMpeg after 2.4.4

FFmpeg is prone to a denial-of-service vulnerability.An attacker can exploit this issue to crash the affected application, denying service to legitimate users. Due to the nature of this issue, code-execution may be possible; however this has not been confirmed.
